SAP Message R7190 - There are no tables to be converted

Diagnosis
At present no tables are reserved for the conversion.
The reservation of tables takes place when activating InfoOjects, ifthe activation of DDIC tables fails because tables need to beconverted. Then, the tables to be converted are saved internally inorder to convert them with the function that you selected.
You either have no InfoObjects (or not the current InfoObject &V1&)activated yet or all DDIC tables could be activated without the needfor conversion.

Procedure
Activate the current InfoObjects (or current InfoObject &V1&).Afterwards you can convert the tables that need to be by calling upthis function again.
